N7 - Hahne-Kedar Facility part 1

To find this side quest, you're going to need to do a little bit of traveling. But first, you'll need to complete the side quest known as N7: Abandoned Research Station. Doing so will give the Normandy's computers electronic intelligence that will ultimately give up the location of the Hahne-Kedar Facility, an infected production line overrun by mechanical enemies that needs to be shut down. To find it once the aforementioned side quest is complete, you'll need to head to the Titan Nebula. Following the jump, you should find yourself in the Haskins system. The small, rocky planet Capek should be easy enough to find from there. Once you're orbiting the planet, find the ground-based disturbance, shoot a probe at it, and then land.

When you gain control of your chosen party on the surface of Capek, it's time to get down to business. Work your way away from your landing craft, and towards the entrance to the facility ahead. As you approach the entrance, a few LOKI Mechs and FENRIR Mechs will poke their way out of the door and assault the party. Use the rocky outcropping around you for protection as you return fire on these elementary enemies. Once they're all downed, and you've survived this decidedly-hostile greeting, you can work your way through the same door the enemies emerged from. This is the facility we're looking to shut down.

As soon as you enter the facility, you'll see what looks to be a downed Asari corpse on the ground in front of you. To your right is a door. Ignore the door for now, and move straight ahead, past the corpse, and into a small office. Here, you'll find a few things of note. You can examine the computer terminal on the left to read a series of messages. Reading each message in sequence will give you a little bit of an idea of what's going on around here. To the right of that is a medical kit; grab the Medi-Gel from within if needed. And finally, a wall safe within this room will surrender a few thousand credits if hacked successfully. Once you've done all of that, retreat into the previous room, and use the previously-mentioned door to head rightward. As you head into this next room, all will be quiet, but you know that it won't last very long. In the meantime, scour the contents of the datapad on your left as you enter the area, since it'll have more information for you.
